Read our Heart Failure research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether personalizing your pacemaker's settings can help you feel better and improve how well your heart works. Instead of using the same standard heart rate setting for everyone, researchers will find the heart rate that works best for your body by testing different speeds and measuring how your heart responds. You'll be randomly assigned to either this customized approach or the standard pacemaker setting, and your health will be monitored for one year.
Most people with a pacemaker get the same basic settings, but recent research suggests that finding each person's ideal heart rate might reduce symptoms and improve heart function. This trial aims to prove whether taking time to personalize your pacemaker actually makes a meaningful difference in how you feel and your long-term health.

After your pacemaker is implanted, you'll wait two weeks for your heart to stabilize. If you're in the customized group, you'll undergo a special heart catheterization procedure where doctors will test your heart at different pacing rates (60, 70, 80, and 90 beats per minute) to find which rate works best for you, then fine-tune around that rate. The standard group will simply have their pacemaker set to 60 beats per minute. Both groups will have regular follow-up visits over the next year to check your symptoms, heart function, and overall health.
